My 13 year old granddaughter is wanting a bass guitar and I'm thinking about buying her one for Christmas. She's musically inclined and is in the 8th grade band and also is in a very good high school marching band playing percussion. I think she's about 5' 6" and has a slim build. I'm guessing she'd be able to play the full scale instead of the short scale because of her size and she'll probably grow some more. I'll probably buy her a used one that's in good shape. I need to be schooled on the lower priced Squier bass guitars. I see Vintage Modified Jaguar, Affinity Precision PJ, Modified, Affinity Jazz, Affinity PJ Bass Limited, Affinity Series J Bass and there may be others. Except for the Jaguar they all look about the same. Are there any appreciable differences between them? Does the short scale have less frets or is it just a shorter neck with less space between the frets? There are two Squier P Bass guitars in the area for $100 and $115 that are supposed to be in good shape. I guessing that these are just older versions of the newer Precision Bass. Would she be just as well off with one of these or should I get her a new one? Well anyway I'd appreciate any information that you people can give me and it'll be appreciated.
